Metal Roofing Project of Bengbu Olympic Sports Center Stadium

The Bengbu Olympic Steel Structure Sports Center is composed of ” three compartments and one bridge” One is for the stadium, two are for the gymnasium and multi-function complex, while the other one is for the sports school. The area of the wall enclosure system of the stadium house is approximately 28,000 square meters; the wall area of the gymnasium house is approximately 18,000 square meters. The wall area of the multifunctional complex building is approximately 13,000 square meters, the roof area of the sports school is approximately 5,000 Square meters, and the roof area of the connecting bridge is approximate: 2400 square meters.

The stadium enclosure system consists of an aluminum-magnesium-manganese metal roofing system, dragon scale aluminum composite panel decoration system, gutter system, and sunshine board system. The sports school enclosure system consists of: an aluminum-magnesium-manganese metal roofing system, aluminum composite board decoration system, gutter system, and cornice system. The composition of the bridge enclosure system: aluminum composite panel decoration system.

The gymnasium project is designed with the sacred animal in traditional Chinese culture-“dragon” as the design concept. The roof and sides are made of aluminum decorative panels, mainly rectangular and rhombus, red and white, superimposed on each other, in a scaly shape, and a bird’s eye view is like a giant dragon. The scales are hung on the ground, and use Rhinoceros5 and parametric software for modeling and blanking. Each dragon scale unit is assembled on the ground and then hoisted as a whole, and only the butt connection is made on the roof wall. The unit installation and construction technology require extremely high construction accuracy and processing accuracy. The roofing system adopts a multi-channel difference adjustment technology, and the positioning of each unit is accurate.
